# Four times the difference of a number and 7 is 12. Find the number.

The question is based on a linear equation in one variable.

## Answer: If four times the difference of a number and 7 is 12, then the number is 10.

Let's find the number which is the solution of the given equation: four times the difference of a number and 7 is 12.

**Explanation:**

Given that, four times the difference of a number and 7 is equal to 12.

Let the number be "a"

4(a - 7) = 12

4a - 28 = 12

4a = 28 + 12

4a = 40

a = 40/4

a = 10

### Thus, 10 is the required number.
